Definitions

  • the present invention relates to a cellular reinforcement for soil particle confinement which is used for environment- friendly protection of a slope and an embankment or for forming the base of a retaining wall, revetment, road, etc., and more particularly, it is formed by interlacing transverse reinforcement cords and longitudinal reinforcement cords with each other to form a netlike sheet having openings of a preset size and by fusion- splicing the sheets formed in this way in a widthwise direction.
  • This confers advantages in that a high coefficient of permeability is obtained, the frictional force with the aggregate is increased, and thus material can be saved to decrease the manufacturing cost. Also, easy root formation is ensured, and the load acting upon the application of compressive stress is dispersed to prevent the deformation of the cellular reinforcement, whereby the ground can be stabilized.
  • a conventional construction of a reinforcement for protecting a slope or an embankment includes band-shaped sheets 100 which are made of polyethylene and have a preset length. These sheets 100 are superposed upon and coupled with one another through ultrasonic welding. Then, by pulling the resultant structure in both directions, a cellular reinforcement for soil particle confinement is formed to have the shape of a cellular net.
  • holes 200 are subsequently punched through the sheets 100 in situ by a worker using a puncher so as to increase the coefficient of permeability of the cellular reinforcement to some extent.
  • the conventional cellular reinforcement has drawbacks in that it has a low coefficient of permeability and small frictional force with respect to a filler, costly equipment is needed to manufacture it, the manufacturing cost increases, easy root formation is not ensured, and the deformation of the sheets 100 occurs upon application of a compressive load, whereby the ground can be made unstable. Disclosure of Invention
  • the present invention has been made in an effort to solve the problems and an object of the present invention is to provide a cellular reinforcement for soil particle confinement which is formed by interlacing transverse reinforcement cords and longitudinal reinforcement cords with each other to form a netlike sheet having openings of a preset size and by fusion-splicing the sheets formed in this way in a widthwise direction.
  • Advantages conferred include obtaining a high coefficient of permeability, increasing the frictional force with aggregate, saving material, thus decreasing the manufacturing cost, ensuring easy root formation, and finally dispersing the load acting upon application of compressive stress to prevent the deformation of the cellular reinforcement, so that the ground can be stabilized.
  • the present invention provides a cellular reinforcement for soil particle confinement.
  • Transverse reinforcement cords and longitudinal reinforcement cords are interlaced with each other to form a netlike sheet having openings of a preset size, and after fusion- welding sheets formed in this way at regular intervals in a widthwise direction, a plurality of honeycombed cell nets is formed by pulling a resultant structure in both directions.
  • the cellular reinforcement for soil particle confinement by the present invention is formed by interlacing transverse reinforcement cords and longitudinal reinforcement cords with each other to form a netlike sheet having openings of a preset size and by fusion-splicing the sheets formed in this way in a widthwise direction. Due to this fact, the present invention confers advantages in that a high coefficient of permeability is obtained, the frictional force with aggregate is increased, material can be saved to thus decrease the manufacturing cost, easy root formation is ensured, and the load acting upon the application of compressive stress is dispersed to thus prevent the deformation of the cellular reinforcement, whereby the ground can be stabilized.

  • transverse reinforcement cords 10 and longitudinal reinforcement cords 20 which are made of polyethylene and have a preset length, are interlaced with each other to form a netlike sheet 40 having a plurality of openings 30 of a preset size.
  • the interlacing pattern of the transverse reinforcement cords 10 and the longitudinal reinforcement cords 20 can be changed between +, x and * shapes.
  • the sheets 40 are connected with one another at regular intervals in the widthwise direction thereof through fusion welding.
  • the fusion welding can be conducted as ultrasonic welding, hot melt welding, hot wedge welding, hot air welding, etc.
